Teacher beliefs and constraints in implementing a context-based approach in chemistry

Context-based chemistry is a new teaching approach which applies the concepts studied to contexts relevant to students. In Queensland a syllabus adopting a context-based approach to Years 11 and 12 Chemistry has been piloted over the last five years in selected classrooms. This article reports on a study evaluating the success of the pilot. The study offers significant support for the value of context-based chemistry in the senior secondary years, while also noting the challenges that the new approach presents for students, teachers and parents

T-Duality and Double Field Theory

The purpose of this thesis is to study a symmetry of string theory known as T-duality. We focus on a particular example establishing the equivalence between a quantized string moving in a circular space of radius R and a dual string moving in a similar space of radius 1/R . We will show that this duality implies that the momentum of the string in one picture becomes the number of times the string is wound around the circle in the dual picture. We present two proofs of T-duality. The first reflects the standard interpretation of T-duality as an isomorphism of quantum theories. The second approach is based on Hull\u27s Double Field Theory

Unethical consumers: Deshopping behaviour using the qualitative analysis of theory of planned behaviour and accompanied (de)shopping

Purpose Previous research indicates that deshopping is a prevalent and growing consumer behaviour. This paper examines deshopping from a consumer perspective, and applies the Theory of Planned Behaviour (TPB) to demonstrate how this behaviour can be managed and prevented. An accompanied (de)shop is also conducted. This paper also places deshopping within a legal and ethical context, in relation to the established literature in this field. Methodology approach This paper tests the TPB variables in a qualitative way by conducting in-depth interviews with deshoppers, who had completed a quantitative questionnaire. The results further support and enhance the quantitative TPB results collected previously with 535 consumers. An accompanied (de)shop is also reviewed, as this qualitative research technique, enables an enhanced understanding and evidence of the deshopping process, which has not been demonstrated previously. The findings demonstrate support for these qualitative research tool, which enable a deeper understanding of the deshopping process and its management. Findings The findings demonstrate important use of the TPB as a qualitative research technique. The model is also expanded and redesigned by adding additional variables as a result of this research. The accompanied (de)shop findings demonstrate support for this qualitative research tool, which also enables a deeper understanding of the deshopping process and its management. Practical implications The research concludes with the implications of deshopping for the industry and makes recommendations as how to reduce deshopping, as well as recommending the qualitative research techniques utilised to future researchers. Originality This paper has identified the key variables that influence deshopping, and demonstrates that procedures can be designed to reduce this behaviour by manipulating the TPB variables. This paper has also added additional variables to the TPB model, which have proved to be influential in deshopping behaviour, thereby developing theoretical knowledge of TPB. The use of the TPB has also provided a theoretical underpinning to utilising a consumer education program to prevent problem behaviours. This research demonstrates that this could alter deshoppers’ attitudes and subjective norms. This is also the first paper to place deshopping in a legal framework which highlights the legal loopholes in a retailer’s returns policy and the implications of new directives which will influence retailer’s abilities to refuse a return. This paper is also the first to explore deshopping within an ethical framework that has created new knowledge on the unethical consumer in relation to deshopping behaviour. This study also incorporates an accompanied (de)shop methodology; this form of research has never been undertaken in relation to deshopping activity and has generated completely new knowledge of what is happening when the actual behaviour is taking place

Interviews of deshopping behaviour: An analysis of theory of planned behaviour

Research reveals alarming results on the prevalence of the dishonest consumer behaviour known as deshopping. Deshopping is the “deliberate return of goods for reasons other than actual faults in the product, in its pure form premeditated prior to and during the consumption experience.” (Schmidt et al., 1999 p.2) In effect this means buying something with no intention of keeping it (Schmidt et al., 1999). The authors consider the implications of deshopping and retailers’ prevention of deshopping, exploring the research undertaken to date and the methodology for further research

Employer Benefits and Costs of English@Work Participation

Evaluation of English@Work’s benefits and costs for participating employers.The Ray Marshall Center (RMC), with support from the Literacy Coalition of Central Texas (LCCT), has conducted an evaluation of English@Work’s benefits and costs for participating employers, a required component of LCCT’s grant from the Houston Center for Literacy-English@Work which was launched as a small nonprofit in Austin in 2005 and was subsumed by the LCCT in January 2014, is a unique approach to teaching English-language skills by contextualizing, customizing, and providing them in the workplace. Early results indicated that this approach substantially outperformed more traditional approaches that rely heavily on classroom instruction, provide few hours of actual instruction per week, and/or fail to contextualize and tailor instruction in the setting and language of the workplace. Students made larger gains on various literacy measure more quickly than these more traditional approaches. And, students indicated that they felt more motivated to learn in a cohort of their peers that was situated within their workplace. After three years evolving and growing under the auspices of the LCCT, the Texas Workforce Commission’s (TWC) Site-based Workplace Literacy Project has provided grant funding to scale up English@Work in Austin and expand it to the Houston area over the period from May 2016 to June 2017. The grant from TWC supports literacy and career services for more than 700 participants and plans to provide credentials or certificates of completion for around 490 of these participants over the grant period.Literacy Coalition of Central Texas and Houston Center for LiteracyRay Marshall Center for the Study of Human Resource

Moving Forward as a Family: Crafting a 2-Generation Strategy for Central Texas, PRP 192

United Way for Greater Austin commissioned this policy research project to guide their focus on helping low socioeconomic families achieve greater financial stability through the development of a Two-Generation (2-Gen) strategy for the Central Texas region. Two-Gen programs emphasize the importance of education as a means for better economic outcomes. High-quality early childhood education programs allow children to make critical neural connections during a period of substantial growth and development, ultimately better preparing them for pre-kindergarten programs and academic success in subsequent years. Adults working low-paying jobs encounter barriers to career advancement due to lacking credentials or relevant education. It is not uncommon for parents working long hours for low wages to have at least one child in need of high-quality early childhood education, yet they are unable to enroll their child in such programs due to issues such as cost, transportation, and time away from work. Two-Gen programs seek to resolve the issues complicating this problem of financial instability by providing high-quality educational and training programs for both parents and children, which are even more effective when intentionally coordinated so that the family develops as a single unit in a positive direction. The research consisted of a literature review; a program scan at the local, state, and federal levels; and site visits within Austin, Dallas, and San Antonio, as well as Boston and Miami. Data collected specific to the Central Texas region include a labor market analysis, a needs assessment, and a mapping of current organizational assets. Obtaining and analyzing this data allowed the team to better understand 2-Gen program development, outcomes, impact measurements, and areas for improvement. The research team developed practical applications for the information collected, ultimately contributing to the proposed anti-poverty strategy through the intentional coordination of 2-Gen services by leveraging existing organizational assets to best address the area’s most salient needs. In addition, the team proposed an evaluation strategy involving cost-benefit equations, program evaluation metrics, and a screening tool to predict the likelihood of a program achieving successful outcomes. The report concludes with policy recommendations at the local, state, and federal levels, as well as a summary of the populations affected by financial instability and future directions for this field.United Way for Greater AustinPublic Affair

The management of deshopping and its effects on services: a mass market case study

Purpose: Deshopping is the return of products, after they have fulfilled the purpose for which they were borrowed. Previous research indicates that deshopping is a prevalent and growing consumer behaviour. This paper examines deshopping from a retail perspective. It is a case study of interviews conducted with a mass-market retailer, to investigate their awareness and management of this behaviour. Methodology: This paper is a case study of nine interviews conducted with different levels of staff at a mass-market retailer in their flagship London store, to investigate their awareness and management of deshopping. Findings: The findings demonstrate the beliefs, attitudes and emotions of the different levels of employees towards deshopping and demonstrates their attempts to manage deshopping and combat the negative affects of this on customer service. Research limitations: The limitation of this research is that it is only conducted with one high street retailer. However, it is important to highlight that this is a large womenswear retailer which is highly representative of other retailers within the sector. There is little detail given regarding the retailer itself or their fundamentals of the actual Customer Service Policy, this is due to the confidentiality agreement between the researcher and retailer. It is important to acknowledge the sensitivity of this type research to retailers who are reluctant to have this information publicised. It is also important to acknowledge that many retailers have not made any attempts to manage this behaviour by restricting their returns policy. So this research case study is conducted with a retailer that is actively introducing change to manage this behaviour. Practical implications: The research concludes with the implications of deshopping and its management and makes recommendations on how to reduce deshopping whilst maintaining customer service for the genuine consumer. Originality/value of the paper: This is the first case study with a mass market retailer highlighting their approaches towards managing deshopping whilst trying to maintain customer service

On the rooted Tutte polynomial

The Tutte polynomial is a generalization of the chromatic polynomial of graph colorings. Here we present an extension called the rooted Tutte polynomial, which is defined on a graph where one or more vertices are colored with prescribed colors. We establish a number of results pertaining to the rooted Tutte polynomial, including a duality relation in the case that all roots reside around a single face of a planar graph. The connection with the Potts model is also reviewed.Comment: plain latex, 14 pages, 2 figs., to appear in Annales de l'Institut Fourier (1999
